ellen needs to buy 180 inches of ribbon to wrap a large present. the store sells ribbons only in whole yards. how many yards does ellen need to buy to have enough ribbon?
1 yard = 36 inches
180 / 36 = ______ yards
180 division by 36 my answer is 5.
To determine how many yards Ellen needs to buy, we need to convert the given inches to yards.
First, let's convert the inches to feet. Since there are 12 inches in a foot, we divide 180 by 12:
180 inches ÷ 12 inches/foot = 15 feet
Next, let's convert the feet to yards. Since there are 3 feet in a yard, we divide 15 by 3:
15 feet ÷ 3 feet/yard = 5 yards
Therefore, Ellen needs to buy 5 yards of ribbon to have enough for the large present.
